See the purity, trust the technology. A tankless under-sink system that delivers ultra-pure, clean, refreshing water on demand—made for North Naples living.
The System Itself
The whole system fits under your sink and connects with quick-connect fittings. Four quick-change twist cartridges provide the four filtration stages, with a UV chamber inline. No bulky storage tank—just fresh, on-demand water for your North Naples home.
The first cartridge catches rust, dirt, and sand—helpful with mineral-rich North Naples water before anything downstream sees it.
Carbon block media that reduces chlorine, odors, colors, and chemicals—great for mineral-rich North Naples water ahead of the membrane.
The heart of the system—rejects dissolved solids and heavy metals, helping tackle North Naples’ mineral-rich water, and sends concentrate to the drain.
The final cartridge polishes the water and adds beneficial minerals back for a balanced pH—great for North Naples drinking water.
Filtration Stages
Each stage handles what the one before it left behind—especially helpful with North Naples’ mineral-rich, hard water. UV is the fourth step in the sequence and the one stage that is not filtration at all; it is there to deal with what a filter cannot catch.
Removes rust, dirt, sand, and large particles—great for mineral-rich North Naples water.

The Mr. Pure Water Under-Sink Reverse Osmosis System with UV Sterilization is a tankless point-of-use system that fits neatly under your sink with quick-connect fittings—ideal for North Naples homes dealing with mineral-rich, hard water. Cold water enters a PP sediment cartridge that catches rust, dirt, sand and large particles, then a CTO carbon block that takes out chlorine, odors, colors and chemicals. The reverse osmosis membrane removes up to 99% of dissolved solids and heavy metals, sending the concentrate to the drain at a 1.5:1 pure-to-drain ratio. A built-in UV lamp then kills 99.99% of bacteria, viruses and microorganisms - the one thing a filter cannot catch - operating automatically on water flow pressure. An alkaline and mineral stage finishes the water, putting beneficial minerals back for a balanced pH. Five stages in all - PP, CTO, RO, UV and alkaline - producing up to 400 gallons a day on demand, with no bulky storage tank to hold water, take up space or invite secondary contamination.
